Mercedes 300SDL Replacement Thermostat Information


The thermostat on your Mercedes 300SDL, unlike your home's wall thermostat, doesn't signal the heater or AC when to turn on and off but, rather, signals your car's engine coolant when to leave the engine and go into the radiator to be cooled off. When the engine is cool, typically below 180 degrees F., the thermostat remains closed and the coolant simply circulates within the engine. Once the engine reaches operating temperature, however, the thermostat opens up to allow the coolant to flow through the hose and into the radiator, where it's allowed to be cooled down.

A faulty thermostat means the engine will either overheat or under-heat, depending on whether it's stuck in the open or closed position. Either way, it needs to be replaced, and PartsGeek.com has the exact replacement part for your 1986 or 1987 Mercedes 300SDL, from either Beck/Arnley or Stant.
